Liquid ester compositions and cosmetic compositions containing the same

ABSTRACT

The present invention provides a liquid ester composition which is obtained by esterifying a branched isostearic acid such as 2-(1,3,3-trimethyl)butyl-5,7,7-trimethyl octanoic acid with dipentaerythritol, and said liquid ester composition having a viscosity at 25° C. of 100,000 to 2,000,000 mPa·s; hydroxyl value of 10 to 160; and cloud point of less than 5° C. This liquid ester composition has pigment dispersibility and hydrating ability that polybutene, which is one of the raw materials of oil compositions for cosmetic compositions, does not have, together with their abilities to sustain feeling of cosmetic film and improve gloss and moisture feeling of cosmetic compositions and shape retaining ability of lipsticks and the like equal to those containing polybutene.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to liquid ester compositions that can be used as raw materials in cosmetic compositions such as makeup, skin care and hair care products; cosmetic compositions that contain the liquid ester compositions; and lasting agents of cosmetic film that contain the liquid ester compositions.

BACKGROUND OF THE INVENTION

Up to now, in order to improve the feeling when using cosmetics, compositions for skin, and the like, especially feeling of cosmetic film, gloss, and moisture feeling, highly viscous hydrocarbon liquid oils such as wax and polybutene have been used. Since polybutene is a raw material that is excellent in improving feeling of cosmetic film and gloss and has a long-lasting feeling of cosmetic film, it is widely used in cosmetic compositions for makeup (Patent Literatures 1, 2 and 3).

However, when increasing an amount of polybutene in the cosmetic compositions in order to further improve the long-lasting feeling of cosmetic film, sticky feeling becomes stronger and the results are not always satisfactory. In addition, the hydrate ability of polybutene is very low because it is a nonpolar liquid oil. As a result, it sometimes causes make-up deterioration caused by perspiration through the skin and the like in case of formulating polybutene in cosmetic compositions or compositions for skin. Thus, polybutene is not always satisfactory in respect of making make-up last longer.

As raw materials of the cosmetic compositions that are excellent in the sense of use such as feeling of cosmetic film and richness, a polyglyceryl isostearic acid using a 2-(1,3,3-trimethyl)butyl-5,7,7-trimethyl octanoic acid as a fatty acid has been developed and reported (Patent Literature 4). However, the viscosity of the polyglyceryl isostearic acid is 35,000 mPa·s at the maximum value, and it cannot be used in cases that use of the products having the high viscosity of 100,000 mPa·s or higher is required in order to further improve functions such as pigment dispersibility and lastingness of cosmetic film.

Besides, oil solvents containing esterified compounds that are composed of multiple branched fatty acids and alcohol have been developed (Patent Literature 5). However, this literature discloses that the viscosity of the obtained esterified compounds is 30,000 mPa·s at the maximum value, and the production methods described therein sometimes generate the products having a high cloud point. Therefore, the products thus produced are not always satisfactory in respect of quality.

Further, the Patent Literature 6 discloses that a 2-(1,3,3-trimethyl)butyl-5,7,7-trimethyl octanoic acid is used as one component of an external drug wherein a medicinal drug is effectively absorbed transdermally or absorbed in the stratum corneum, but any study therein on the ester compositions obtained by esterification with alcohols has not been made.

Next, the liquid ester compositions of the present invention can be used as lasting agents of cosmetic film.

This is because the liquid ester compositions of the present invention have a high viscosity of 100,000 mPa·s or higher, and adhesion ability of the cosmetic film to skin is high. As a result, the compositions have an effect of sustaining cosmetic film and can make makeup last longer. The liquid ester compositions of the present invention can be lasting agents of cosmetic film by itself or combined with one or more kinds of other components such as liquid fats and oils, liquid waxes, liquid hydrocarbon oils, liquid higher fatty acids, liquid higher alcohols, isopropanol, liquid ester oils, silicon oils, antioxidants and ultraviolet absorbers. Here, the liquid components indicate those that are liquid at room temperature. As for the liquid fats and oils, isopropanol, silicon oils, antioxidants and ultraviolet absorbers, the same ones can be used as those mentioned in the cosmetic compositions containing the liquid ester compositions. As for the liquid waxes, liquid hydrocarbon oils, liquid higher fatty acids, liquid higher alcohols and liquid ester oils, the liquid components at room temperature can be used among those mentioned in the cosmetic compositions containing the liquid ester compositions.

The content of the liquid ester compositions of the present invention in the lasting agents of cosmetic film is preferably 50 to 100 mass %, more preferably 70 to 100 mass % and most preferably 80 to 100 mass %.

The lasting agents of cosmetic film of the present invention can be used in the cosmetic compositions such as cosmetic compositions for makeup, emulsions, cream, sunscreen agents and cosmetic compositions for hair. The cosmetic compositions for makeup and hair are the same ones as those mentioned in the cosmetic compositions containing the liquid ester compositions.

The liquid ester compositions of the present invention can sustain feeling of cosmetic film and improve shape-retaining ability of lipsticks and the like. Therefore, cosmetic compositions for makeup, emulsions, cream, sunscreen agents and cosmetic compositions for hair that have an excellently long-lasting makeup can be provided by using the liquid ester compositions of the present invention.

Besides, since the liquid ester compositions of the present invention have pigment dispersibility, they can stably disperse pigments in the cosmetic compositions. In addition, since the liquid ester compositions of the present invention also have hydrating ability, they can provide gloss and moisture feeling to oily cosmetic compositions.

The evaluation of the pigment dispersibility was conducted by measuring length (mm) of the transparent separate phase of oil, which is produced on the upper part of a pigment dispersion liquid caused by sedimentation of pigments. Further, liquid paraffin was used as an evaluation sample, and put into a thermostat bath kept at 40° C., left at rest and stored for 24 hours. The length of 100 mm of the transparent separate phase of oil, which is produced on the upper part of a pigment dispersion liquid is regarded as a sedimentation rate of 100%. The sedimentation rate after one hour was calculated from the following formula and the evaluation was conducted based on the judgment standard shown in Table 1. Here, A=length (mm) from the liquid level after leaving an evaluated sample at rest at 40° C. for one hour; and B=length (100 mm) from the liquid level that transparently separated after leaving an evaluated sample that was dispersed in liquid paraffin only at rest, and storing it at 40° C. for 24 hours.

Sedimentation rate (%)=A/B×100

The results of the pigment dispersibility evaluation are shown in Table 2. As clarified from the results, the liquid ester compositions 1 to 3 are excellent in dispersibility of titanic oxide that is an inorganic pigment, which is typically regarded as being difficult to maintain the dispersion state. In contrast, the dispersibility of titanic oxide was not satisfactory in the comparative liquid ester composition 1, diglyceryl triisostearate using an isostearic acid that has the same branched structure as those of the liquid ester compositions 1 to 3, and diisostearyl malate generally used as a raw material of cosmetic compositions. As for hydrogenated polybutene, no dispersibility was seen.

The evaluation was made to the liquid ester compositions 1 to 3, comparative liquid ester composition 1, diisostearyl malate (trade name: Cosmole 222 produced by the Nisshin OilliO Group, Ltd.), diglyceryl triisostearate using an isostearic acid that has the same branched structure as those of the liquid ester compositions 1 to 3 (trade name: Cosmole 43N produced by the Nisshin OilliO Group, Ltd.), hydrogenated polybutene (trade name: Parleam 24 produced by NOF Corporation) and Vaseline (trade name: Nomcort W produced by the Nisshin OilliO Group, Ltd.).

2. Evaluation Method

The evaluation of hydrating ability was made based on the values obtained by measuring the water absorption capacity in accordance with the measurement of water absorption capacity of lanolin in the British Pharmacopoeia. The specific evaluation method is described as follows.

1 g of an evaluated sample and 9 g of Vaseline (trade name: Nomcort W produced by the Nisshin OilliO Group, Ltd.) as an oil diluent were collected to a 100 mL stainless beaker, heated up to 80° C., and dissolved and mixed uniformly to prepare a uniform sample. Next, the obtained sample was cooled down to room temperature and Vaseline-like solidification thereof was confirmed. Then, 0.1 to 0.5 g at a time of purified water was added dropwise to 10 g of the sample in a thermostat bath kept at 40° C. The purified water was kneaded with stirring by a stainless propeller(s), and the end-point was determined when purified water could not be kneaded into the sample.

The water absorption capacity (mass %) of an evaluated sample was calculated from the following formula and the evaluation of hydrating ability was conducted based on the evaluation standard shown in Table 3. Meanwhile, the hydrating ability was evaluated as high when the sample had a high value of the water absorption capacity (the standard is 100% or higher).

Water absorption capacity (%)=A total additive amount (g) of purified water/weight of the sample (10 g)×100

TABLE 3 Evaluation Standards of Hydrating Ability Water absorption capacity (%) of the sample Indication of evaluation 100% or higher ◯ 40% or higher and not higher than 100% Δ Not higher than 40% X [Results of the Hydrating Ability Evaluation]

The results of the hydrating ability evaluation are shown in Table 4. As clarified from the results, the liquid ester compositions 1 to 3 obtained in the present invention had a high water absorption capacity just as diglyceryl triisostearate using an isostearic acid that has the same branched structure as those of the liquid ester compositions 1 to 3 did, and, therefore, they had an excellent hydrating ability. In contrast, the water absorption capacities were low in the comparative liquid ester composition 1 wherein pentaerythritol was used instead of dipentaerythritol and diisostearyl malate generally used as a raw material of cosmetic compositions, and, therefore, their hydrating abilities were not satisfactory. As for hydrogenated polybutene, no hydrating ability was seen.

2. Evaluation Method

10 g of an evaluated sample and 10 g of various oil solvents ((1) isopropanol, (2) castor oil, (3) glyceryl tri2-ethylhexanoate, (4) liquid paraffin and (5) 10 cs dimethylsiloxane) were collected to a corked sample bottle, heated up to 70° C. and forcibly mixed by shaking the mixture up and down by hand for about 5 minutes. Then, the mixture was put into a thermostat bath, left at rest and stored for 15 minutes. After warming the reactant to room temperature, it was left at rest for 2 days. Then, its appearance was observed and the evaluation was made based on the judgment standard shown in Table 5.

TABLE 5 Evaluation Standards of Compatibility Status of the liquid mixture after 2 days Indication of evaluation Transparently compatible ◯ Clouded or separated X [Results of the Compatibility Evaluation with Various Oil Solvents]

The results of the compatibility evaluation with various oil solvents are shown in Table 6. As clarified from the results, the liquid ester compositions 1 to 3 in the present invention uniformly mutually dissolved in all of the oil solvents (1) to (4). Therefore, it was clarified that they could be formulated into various cosmetic compositions. Particularly, since the liquid ester composition 1 mutually dissolves with dimethylsiloxane having a low viscosity of the oil solvent (5), it can be formulated into skin care products containing dimethylsiloxane having a low viscosity and foundation.

Besides, since the liquid ester compositions 1 to 3 have a high compatibility with isopropanol, they can be used as a raw material for the surface treatment of powders, and the surface treated powders using the liquid ester compositions can be used in the cosmetic compositions.

On the other hand, as the comparative liquid ester composition 1 and hydrogenated polybutene do not have compatibility with castor oil, in case of formulating them into the cosmetic compositions, ingenuity is required such as combining with the other raw material(s). Therefore, it was clarified that use thereof was limited in respect of formulation.

Meanwhile, in the table, the oil solvent (1) is isopropanol (produced by Wako Pure Chemical Industries, Ltd.); the oil solvent (2) is castor oil (trade name: Purified Castor Oil, produced by Hokoku Corporation); the oil solvent (3) is glyceryl tri2-ethylhexanoate (trade name: T.I.O. produced by the Nisshin OilliO Group, Ltd.); the oil solvent (4) is liquid paraffin (trade name: Silkool P-70 produced by Matsumura Oil Co., Ltd.); and the oil solvent (5) is 10 cs dimethylsiloxane (trade name: KF-96 10CS produced by Shin-Etsu Chemical Co., Ltd.).
